I have a CSV of contacts that I want to import. Some of the Contacts already exist and some do not. Some appear in the CSV more than once because they have relationships to multiple accounts. My CSV already contains the salesforce ID to indicate which Accounts they need to be associated with. Because some of them may already exist, can an upsert be done that adds them as an indirect contact on the Account if they already have a direct relationship to an Account? How does data loader deal with such relationship details? #Data Management #Data Import

Hello,
You should be able to upsert account contact relationships to achieve this.
However, you would need to upsert contacts first to make sure they all exist and have an ID because this is needed for the account contact relationships.
